WAAS G-III Receiver
The WAAS G-III provides accurate reference range measurements and signal quality measurements for ground reference networks. Designed for Satellite-Based Augmentation Systems (SBAS) that generate correction data and monitor signal integrity for safety-of-life applications, the WAAS G-III Receiver incorporates design features and signal processing techniques that have been proven and refined over three generations of development and testing.
Independent acquisition and tracking of GPS L1 C/A, L1C, L2C, L5 and GEO L1 C/A and L5 signals
Semi-codeless tracking of L2-P(Y) signals
Temperature controlled RF deck to minimize code and carrier phase shift
Chip-shape signal deformation measurements based on NovAtel Vision™ technology
Signal Quality Monitoring (SQM) measurements based on correlation peak shape measurements
RF interference protection and digital pulse blanking
Advanced cross-correlation and side lobe tracking detection
Adaptive phase-locked loop bandwidth for tracking in high-scintillation environments
Support for memory-based codes for experimental and maintenance activities
Support for modernized GPS signals
The WAAS G-III supports tracking, measurements, and integrity monitoring data for the modernized GPS signals. In particular the added support for the L5 signal allows for the evolution of ground systems to provide dual-frequency SBAS support for civil aviation applications.
